Applications of the Drill Pipe in API 5DP

The drilling tool is connected drill rod for transferring power. The drill string is usually part are: drill, drill collars, drill pipe, stabilizers, special connectors and Kelly. The basic role of the drill string are: (1)control the drill bit; (2) imposed WOB; (3) transmission of power; (4) transporting drilling fluid; (5) special operations: extrusion of cement, handling underground accidents.

API 5DP drill pipe is trailing with screw thread for connecting the drilling rig located at the bottom of surface drilling equipment and mill equipment or bottom outlet device. The purpose is to drill the drilling mud delivered to the drill bit, and drill with the increase, decrease or rotating bottom outlet means. Drill pipe must be able to withstand great external pressure, twisting, bending and vibration. In the mining and oil and gas refining process, the drill pipe can be used multiple times.
